Yes please, your Tested-by would be very helpful.

It is basically the same as my patch above, I just sent it as a formal patch.

Since you said that it does indeed work for you, it does seem like a much
better solution. (Because if we would have reverted the patches, we would
have wanted to reapply them some time in the future.)

Kind regards,
Niklas
